Gyroball RPM
Android app that measures a gyroball's RPM in real time from camera and audio frequency.
- React Native
- Kotlin
- Monorepo
Setup
- Problem
Gyroball users had no objective way to measure their own RPM.
Build
- What I did
- 4-environment monorepo plus a Kotlin native module
- Frequency analysis from camera and audio signals
- QA considerations
- Is it reproducible under the same conditions - a consistent error pattern matters before accuracy (the precondition for correction)
- Do the two signal sources (camera and audio) agree on the same RPM without diverging under lighting/noise changes?
- In the 4-environment monorepo, do the Kotlin native module and the RN layer build and behave identically per environment?
